November 26, 2016 – Analogue Inputs

Analogue Inputs on the Pi

  • Saturday, November 26, 2016

  • Q-College

    Suite 303 771 Vernon Ave, Victoria, BC (map)

  • The Raspberry Pi has 30 GPIO pins, but none of them are analogue inputs. At this meeting, we’ll take a deeper look at how to take an analogue signal (like temperature) and connect it to the Pi, and access it via Python.

November 12th Meeting: IoT Streaming

Raspberry Pi and IoT Streaming

The Internet of Things (IoT) is a hot topic. Join us, as we continue to explore the vast world of IoT using the Raspberry Pi. This weeks session will focus on IoT devices streaming data over the internet.

October 22, 2016 – Python 5: Exceptions

Python provides for the raising and handling of exceptions. An exception is used primarily for managing an error situation but is also handy in other circumstances e.g. an exception is used internally to end loop iteration.

A full writeup for this session is available here.

September 24, 2016: Python 4: Input and Output

Introduction

Welcome back to the Python presentations!

It’s been a while so first a short(ish) recap of the previous 3 presentations, including in more detail the Input And Output section of session 3. Then I’ll discuss some useful Python Tutorials. And finally, we can go on to cover some further aspects of the language.

Serving The Web With A Slice Of Pi

Although small in size, the Raspberry Pi and other embedded Linux boards can be used as very capable web servers.

Instructor Don Woods will show you how to set up a Web server on a Raspberry Pi and get around the little snags to be able to access your Pi from outside your local network.

The entire tutorial is available here:

Note: This will be our last Meetup before the summer holiday season. We will reconvene in early September. Have a good summer, y’all!

June 25th Meeting

Low-cost High-quality PiFi Audio

Presented by Stuart Hertzog

Tired of iTunes? Time for PiTunes! — HiFi audio from your Pi.

You don’t need a PC or laptop to enjoy listening to hifi audio from your personal collection or Internet streaming. And you won’t have to endure the convoluted iTunes interface.

A low-cost Digital Audio Converter (DAC) or DAC and Amplifier such as offered by HiFiBerry or IQAudio will turn any Raspberry Pi2 or 3 into a low-cost and energy-efficient MPD audio server controlled from a Web browser or an iOS/Android app.

Join us as instructor Stuart Hertzog explains how to set up a DAC on your Pi and demonstrates the free and open-source Linux audio software PiMusicBox, Volumio, RuneAudio, and MoOde Audio.

Discover PiFi audio and a world of listening pleasure!

Pi Weather Station Part 1: Temperature and Humidity

Instructor Deid Reimer will demonstrate how to:

  • Measure temperature and humidity with the Pi
  • upload the information for display to a web server and
  • display the information in text and graphical form.

May 14th Meeting

Using the GPIO Pins on the Pi – Part 2

By Deid Reimer

This meeting we’ll pick up on the Pi GPIO pins (Part 2), looking at input, using switches (push buttons). You’ll learn how to not only have your Pi illuminate lights or close relays, but also to take input via GPIO. Using the input and output GPIO capabilities of the Pi, one can create a home automation system, or even replace your “Nest” thermostat with the Pi.

Bring your Pi and get hands on help after the presentation.
